Software documentation for the IRCObject class
IRCObject.h

IRCObject handles all aspects of an IRC connection. In almost all cases, you will want to override this class and implement just the callback methods specified in IRCObject(Callbacks)to handle everything.

A lot of arguments may not contain spaces. The general procedure on processing these arguments is that the method will cut the string off at the first space and use the part of the string before the space and fail only if that string is still invalid. Try to avoid passing strings with spaces as the arguments to the methods that warn not to.

Software documentation for the IRCObject(Callbacks) category
IRCObject.h
This category represents all the callback methods in IRCObject. You can override these with a subclass. All of them do not do anything especially important by default, so feel free to not call the default implementation. On any method ending with an argument like 'from: (NSString *)aString', aString could be in the format of nickname!host. Please see the documentation for ExtractIRCNick() , ExtractIRCHost() , and SeparateIRCNickAndHost() for more information.
CTCPReplyReceived:
aCTCP
withArgument:
anArgument
to:
aReceiver
from:
aPerson
Called when a CTCP reply has been received. The CTCP reply type is stored in aCTCP with its argument in anArgument. The actual location that the CTCP reply was sent is stored in aReceiver and the person who sent it is stored in aPerson.
CTCPRequestReceived:
aCTCP
withArgument:
anArgument
to:
aReceiver
from:
aPerson
Called when a CTCP request has been received. The CTCP request type is stored in aCTCP (could be such things as DCC, PING, VERSION, etc.) and the argument is stored in anArgument. The actual location that the CTCP request is sent is stored in aReceiver and the person who sent it is stored in aPerson.
actionReceived:
anAction
to:
aReceiver
from:
aSender
Called when an action has been received. The action is stored in anAction and the sender is stored in aSender. The person or channel that the action is addressed to is stored in aReceiver.
channelJoined:
aChannel
from:
aJoiner
Called when someone joins a channel. The channel is stored in aChannel and the person who joined is stored in aJoiner.
channelParted:
aChannel
withMessage:
aMessage
from:
aParter
Called when someone leaves a channel. The channel is stored in aChannel and the person who left is stored in aParter. The parting message will be stored in aMessage.
couldNotRegister:
aReason
This method will be called if a connection cannot register for whatever reason. This reason will be outlined in aReason, but the best way to track the reason is to watch the numeric commands being received in the -numericCommandReceived:withParams:from: method.
errorReceived:
anError
Called when an IRC error has occurred. This is a message sent by the server and its argument is stored in anError. Typically you will be disconnected after receiving one of these.
invitedTo:
aChannel
from:
anInviter
Called when the client has been invited to another channel aChannel by anInviter .
messageReceived:
aMessage
to:
aReceiver
from:
aSender

modeChanged:
aMode
on:
anObject
withParams:
paramList
from:
aPerson
Called when the mode has been changed on anObject. The actual mode change is stored in aMode and the parameters are stored in paramList. The person who changed the mode is stored in aPerson. Consult RFC 1459 for further information.
newNickNeededWhileRegistering
Called when a new nickname was needed while registering because the other one was either invalid or already taken. Without overriding this, this method will simply try adding a underscore onto it until it gets in. This method can be overridden to do other nickname-changing schemes. The new nickname should be directly set with -changeNick:
nickChangedTo:
newName
from:
aPerson
Called when someone changes his/her nickname. The new nickname is stored in newName and the old name will be stored in aPerson.
noticeReceived:
aNotice
to:
aReceiver
from:
aSender
Called when a notice aNotice is received from aSender. The person or channel that the notice is addressed to is stored in aReceiver.
numericCommandReceived:
aCommand
withParams:
paramList
from:
aSender
Called when a numeric command has been received. These are 3 digit numerical messages stored in aCommand with a number of parameters stored in paramList. The sender, almost always the server, is stored in aSender. These are often used for replies to requests such as user lists and channel lists and other times they are used for errors.
pingReceivedWithArgument:
anArgument
from:
aSender
Called when a ping is received. These pings are generally sent by the server. The correct method of handling these would be to respond to them with -sendPongWithArgument: using anArgument as the argument. The server that sent the ping is stored in aSender.
pongReceivedWithArgument:
anArgument
from:
aSender
Called when a pong is received. These are generally in answer to a ping sent with -sendPingWithArgument: The argument anArgument is generally the same as the argument sent with the ping. aSender is the server that sent out the pong.
quitIRCWithMessage:
aMessage
from:
aQuitter
Called when someone quits IRC. Their parting message will be stored in aMessage and the person who quit will be stored in aQuitter.
registeredWithServer
This method will be called when the connection is fully registered with the server. At this point it is safe to start joining channels and carrying out other typical IRC functions.
topicChangedTo:
aTopic
in:
aChannel
from:
aPerson
Called when the topic is changed in a channel aChannel to aTopic by aPerson.
userKicked:
aPerson
outOf:
aChannel
for:
aReason
from:
aKicker
Called when a user has been kicked out of a channel. The person's nickname is stored in aPerson and the channel he/she was kicked out of is in aChannel. aReason is the kicker-supplied reason for the removal. aKicker is the person who did the kicking. This will not be accompanied by a -channelParted:withMessage:from: message, so it is safe to assume they are no longer part of the channel after receiving this method.
wallopsReceived:
aMessage
from:
aSender
Called when a Wallops has been received. The message is stored in aMessage and the person who sent it is stored in aSender.
Software documentation for the IRCObject(LowLevel) category
IRCObject.h
This is the lowlevel interface to IRCObject. One method is a callback for when the object receives a raw message from the connection, the other is a method used to write raw messages across the connection
lineReceived:
aLine
Handles an incoming line of text from the IRC server by parsing it and doing the appropriate actions as well as calling any needed callbacks. See [LineObject -lineReceived:] for more information.
writeString:
format
Writes a formatted string to the connection. This string will not pass through any of the callbacks.
Software documentation for the NSString(IRCAddition) category
IRCObject.h
Additions of NSString that are used to upper/lower case strings taking into account that on many servers {}|^ are lowercase forms of []\~. Try not to depend on this fact, some servers nowadays are drifting away from this idea and will treat them as different characters entirely.
lowercaseIRCString
Returns a lowercased string (and converts any of []\~ characters found to {}|^ respectively).
lowercaseStrictRFC1459IRCString
Returns a lowercased string (and converts any of []\ characters found to {}| respectively). The original RFC 1459 forgot to include these and thus this method is included.
uppercaseIRCString
Returns an uppercased string (and converts any of {}|^ characters found to []\~ respectively).
uppercaseStrictRFC1459IRCString
Returns a uppercased string (and converts any of {}| characters found to []\ respectively). The original RFC 1459 forgot to include these and thus this method is included.
